PSTV have two internal user storage mount points: ux0 (without Memory Card, after insert one, this become imc0 and real become ux0) and ur0. I want only redirect MicroSD adapter to uma0. Can I ignore all other parrams and use GCD=uma0 or I need all parrams in config? If all, then how to deal with ur0 and ux0 as I don't want change them?

It comes with "storage_config.txt":

Code:

MCD=uma0
INT=imc0
GCD=ux0
UMA=grw0

Is this correct? I don't want change ux0 and ur0. Also I don't want test it blindly so that's why I'm create this thread.

Code:

MCD=ux0
INT=imc0
GCD=uma0
UMA=grw0

How to configure StorageMgr ?

On each line you have to write following this structure : =<mount_point>

Second code is about right for what you want to do, except that grw0 mountpoint is the official gamecard user writable partition (not all games have this active), I wouldn't have this active. are you using sd2vita right? i would advise to instead use an external HDD, since it's much faster than an sd card, bigger than an sd card and have longer lifespan (in terms of R/W cycles) than an sd card.

@kadorna2 I know, but I wrote it only in case if all parrams must exist. Also I don't play any games for Vita on PSTV so I don't really care of gro/grw (all multiplatform games I finished on PS3 and those few exclusives I already played).

Yes, SD2Vita. Writing speed is for me sufficient what SD to offer but I don't know how fast is GameCard port and how fast is the adaptor. If this would be ~10MiB/s in read and at least half of this in write then it is sufficient. Cell life span is important so it is one of the reasons why I want use uma0, instead to ux0 (other reasons are I don't need such huge capacity for homebrew, 32GiB is sufficient, and I need free USB port to charge DS3).
